Role and deficiency of potassium fertilizer

Potassium is one of the three major elements of fertilizer. Potassium content in plants generally accounts for 0.2% ~ 4.1% of dry matter weight, second only to nitrogen. Potassium is involved in the activation of more than 60 enzyme systems, photosynthesis, assimilate transport, carbohydrate metabolism and protein synthesis during plant growth and development. In the fertilizer industry, potassium is often used as the main raw material and processed into special fertilizer products through NPK fertilizer granulator.

Main function of potassium fertilizer

1. Promote enzyme activation

Potassium fertilizer activating enzyme is one of the most important functions of potassium in plant growth. So. Potassium is closely related to many metabolic processes in plants, such as photosynthesis, respiration and the synthesis of carbohydrates, fats and proteins.

2. Promote photosynthesis and transport of photosynthetic products

It can improve photosynthetic efficiency, adjust stomatal opening and closing, and control the inflow and outflow of carbon monoxide and water. It can promote the synthesis of carbohydrates and accelerate the flow of photosynthetic products.

3. Promote protein synthesis

No ₃ is a key component of protein synthesis, and its uptake and transport are closely related to the process of protein synthesis.

4. Enhance the stress resistance of plants

Potassium can reduce soluble amino acids and monosaccharides, increase cellulose and thicken cell wall; Potassium can produce osmotic pressure gradient in crop roots and enhance water absorption capacity; Potassium can close the stomata of crop leaves and prevent water loss during drought and water shortage. Therefore, potassium can enhance the disease resistance, cold resistance, drought resistance, lodging resistance and salt resistance of crops.

Harm of excessive application of potassium fertilizer

1. Excessive potassium application will not only waste valuable resources, but also reduce the absorption of cations such as calcium and magnesium by crops, resulting in “heart rot” of leafy vegetables and “bitter pox” of apples.

2. Excessive application of potassium fertilizer will cause soil environmental pollution and water pollution.

3. Excessive application of potassium fertilizer will weaken the production capacity of crops. Therefore, modern industry uses fertilizer production lines to mix NPK fertilizer in proportion. The proportion of each element in the formula is different according to different regions and fertilizer characteristics. The chemical fertilizer granulator makes different raw materials into granules to avoid the harm of chemical fertilizer raw materials.

Tips to make high nutrient organic fertilizer

Organic fertilizer has more nutrients and high content of organic matter. It can also loosen soil, improve soil fertility and improve soil structure. Organic fertilizer is favored by producers and producers to improve crop yield and quality. Since organic fertilizer is so good, do you know how to do it?

The main production process of organic fertilizer production line is to convert raw materials into semi-finished products. In the actual production process, the flat stack composting technology and tank aerobic fermentation process are mainly used.

In addition, the relevant experiments of organic fertilizer equipment can also be produced by small tank fermentation and closed box fermentation.
Process flow of organic fertilizer production line:

Raw material selection > drying and sterilization > fermentation > grinding > stirring > granulation > drying > cooling > coating > screening > metering and sealing > finished product warehousing.

Organic fertilizer production line

1. Tanker:

The can turnover machine is mainly used to help fermentation and decomposition proceed quickly. At the same time, oxygen can enter the reactor to avoid the smell produced by anaerobic reaction.

2. Forklift batching:

The blanking shall be uniform and continuous to avoid hindering the normal operation of the next equipment due to excessive materials.

3. High humidity material crusher:

During the composting process, the agglomerated materials are crushed evenly to reduce the diameter of the materials.

4. Drum screen:

The impurities and bulk materials not crushed are screened out to further improve the marketability.

5. Horizontal mixer:

If it is necessary to improve nutrient elements or produce standard organic fertilizer manufacturers, N, P, K, etc. need to be added.

6. Nitrogen, phosphorus and potassium fertilizer granulator:

Including various fertilizer granulation equipment, flat mold granulator, organic fertilizer granulator, disc granulator and drum granulator.

7. Drum drying cooler

8. Automatic packing scale:

After packaging, it is easy to store. At the same time, it will not cause dust pollution and waste during transportation.
